"It's about being safe. It's about knowing what your own ability is before you go into that water," Heidi Pare said.

She works for the Kennebunk Beach Improvement Association and trains lifeguards throughout southern Maine.

On Sunday, a man at Wassamski Springs Campground in Scarborough over the weekend. Police said Giot, Nguyen, 45, of Portland, had been drinking before he went swimming.

Pare had three tips for parents heading to the beach or a swimming pool. First, set parameters, tell children how far out they can go. Second, know the conditions, such as weather or not the beach has an undertow. Third, supervise and know what swimmers are up to at all time.

At Pine Point in Scarborough, one swimmer had advice to share.

"I would say comfort level is what you should be most concerned with when you're swimming in the ocean," Abbey O'Brien said.

When it comes to children, Pare suggested that knowing how to paddle or do a few strokes was not enough.

"Not only does a child need to be able to swim, they need to be able to save themselves,"Heidi Pare said.

Pare also had advice if someone appears to be drowning.

"If going to put two people in danger than absolutely not, you do not want to go in and try to make that rescue," she said.
